Abstract: A method for fabricating lithium batteries comprising providing a P2O5 drying aid between an exterior surface of a cell laminate and an interior surface of a container in which the cell laminate is sealed. A cell laminate is first formed from a transition metal chalcogenide positive electrode and a carbonaceous negative electrode with an electrolyte-containing separator there between. The cell laminate is then sealed in a container together with the P2O5 drying aid such that P2O5 is available during battery operation to react with moisture generated during charging and discharging of the battery cell.

Abstract: A lithium battery having a separator capable of storing excess lithium ions. As lithium ions are irreversibly adsorbed by the battery electrodes, they are replenished from the excess lithium stored in the separator material, thereby extending battery life. In an example of the present invention, molecular sieves, such as 13X molecular sieves, are used as the separator material. Molecular sieves are hydroscopic and therefore also react with moisture in the battery, thereby reducing cell impedance.

Abstract: A composition for forming an electrode for use in a torch jet spark plug is provided. The composition comprises a ceramic material, ceramic particles, and an electrically conductive material. The ceramic particles are dispersed within the ceramic material. At least some of the ceramic particles have a predetermined size. This predetermined size is at least as large as the thickness of the finally formed electrode. The electrically conductive material is capable of being manipulated to form ribbons around the ceramic particles and of being sintered to form the electrode. The resultant electrode has good resistance to explosive erosion mechanisms, which consequently increases the life of the torch jet spark plug.

The reactive inhibitive coating prevents the reaction of compounds with acids(e.g., phosphates) in the exhaust gas, which may form a dense glass layer on the outside of the gas sensor. The reactive inhibitive coating is either an alkaline earth oxide ethoxide, and/or carbonate that is deposited on the gas sensor to a thickness so as to preferably provide an excess of either the alkaline earth material.
